I use MR gasket 108. Trim the outside with a razor knife when assembled. The 1211 has a larger port openingbthan I like. Jeff

Thanks guys. That's good enough for me. Jeff yours is an 06A too maybe second or third week build?

Around the 23rd

That's what's on mine but a 661 VIN. Probably too late for yours. Jeff

69. Never have found found a use for the 73.
Both of you need the same length but different
Due to years.Jeff

Sealed power, Speed pro and TRW are all morphed into the same CO, Federal Mogul.Speed Pro is the performance line of Sealed Power.Me personally use Diamonds. 1/16 ring package with no issues and are significantly lighter than the originals.About $800 a set.Jeff

Only 68 and 69 ,67 was electric.Jeff

 ;DNE spring source please reply as you are closer to me by far.Jeff

Yes,they came with 880 & 881s from GM in the 70's right after they discontinued the RS only fronts

Yes the end on the speedometer is different.67-68 screws on. The 69 pushes on and held with a clip.Jeff

I believe that is the smaller fan and clutch not the 67-68 Z parts.That Z clutch is 7 1/2" in dia.Please correct me if I am wrong.Jeff

Contrary to what some say the 67 L 78 had a 3 inch BC clutch fan with 5 rivets in an x pattern. pic available.There is a diff in the clutch BB vs SB in shaft length.The 68 belt is longer to fit the 387 pulley.Jeff

If you use the 387 pulley the belt does'nt fit. They will also say the 67 L 78 had the Z 3.25 BC fan on it too.Jeff

If you get a zero I might have a spare.Jeff

Pic as requested of original.Jeff

The original pulley has a stamped number on the front.The NOS that I have does not.Jeff
